Nothing will happen to anyone in this hisar (Hisar means to encircle) except death. Do this to your house especially your children and your family.
Darood/Selavat 1 time
Surah Fatiha 1 time
Ayetal Kursi 1 time
4 kul (Surah Ikhlas, kafiroon, falak , Nas) 1 time each
Darood/salavat 1 time
Then in your imagination make a circle around everything you want to protect. Your children, house, family etc……complete the circle in your imagination.
Everybody and everything in that circle will remain in Allah’s protection for one day.
The day you will have any problem you will realize that you forgot to do the hisar that day.
If this hisar is done around a dead person Allah will stop the azab for one day as well.
